latch 1 7 for retaining the gate in closed poi sition and akeeper 'latchmechanisinlSfor retaining the gate in lopen positionas shownv by 'dottedlines in Figure l. Whilethegconnections between the tripfdevices,`tliefglate' and-fthe latch devices are referred'to as'co'rds',

it is to beunderstood that any cfjrmo'iy connection such as chains orwiresimay be 9111-5 ployed. f 9 The gate l() is journaled at'its upperend as at vieviiithe top wail 0f thefhou'singeo thatis mounted on thelower housing'l, theY lower hinged end of the gateA carryiiiga disk 2lhaving one end 'of a ycoil spring 122 "se-V cured theretow'ith "the*other "end oifthe spring anchoredfwithii'i the-housing l'as at therein,the operating cord for the gate exy 23, to place the gate under tensionfor normally holding the same in its closed position. When the g'a-te isin closed position extending across the roadway 16 as shown in Figures 1and 7, the keeper mechanism 17 embodying a vertical standard 24 has anoverbalanced lever latch 25 pivoted thereto as at 26 with the forwardlyprojecting end of the latch 25 positioned for engagement with thebeveled keeper lug 27 carried by one face of the gate 10, the spring 22moving the gate to itskclosed position and causing the lever latch 25 toride over the beveled nose of the keeper lug 27 In order to effect anopening movemento-f the gate against the tension of the spring 22, thetrip devices 14 and 15 as above described are positioned at oppositesides ofk the gate and, have cordconnections with the disk 21 associatedwith the gate hinge.- These cord connections are more clearly shown inFigure 1, the same extending from the trip devices to the housing 13 andinterconnected tendingfrom'the trip device 15 being designated by thereference character -aas passing through the opening 28 in the wall 12of the housingV 13 and traversing the bracket supported pulley 29 asshown in said figure and further passes over the bracket supportedpulley 3() with the portion designated -battached to the gate disk 21.

The cord intermediate the pulleys 29 and 30 has connected thereto as ata a cord -cthat extends to the opposite end of the housing 13 `forpassage over the bracket supported pulley 31 and the end CZ- of the cord-c-e yet the pulley 31 is attached to the latch mechanism that holds thegate in open position to be later described, and as shown in Figure 2.It will therefore be seen that Vthe Yoperating cord extending from thetrip is connected to the gate for moving e the same to open position andalso is connected to the latch mechanism for releasing the gate from itsopen position.

lA similar cord arrangement extends from the vtrip device 14 t0 the gate1() and gate releasing latch mechanism 1S, the same being designatedV bythe reference numeral 1 as entering the opening 32 in the wall 12`of thehousing 13 and passesover the bracket supported pulley 33 and continuesas indicated by the reference numeral` 2 for passage over the bracketsupported pulley 34, and further passes over the bracket supportedpulley 35 and reversely travels as indicated by the numeral 3 forconnection as at 2 with the Vcord section -c-. A cord 4 is connectedl asat 4 to the cord section 2 and passes over Ythe bracket supported pulley36 with the free endy 5 thereof secured to the disk 21 of the gate.Similar to the cord connection -a-' between the trip devices 15 and. thegate 10 and latch mechanism 18, is

v.locking arm 39 is slidably mounted.

the cord connection Z-. The cord -Z- .entering the housing 13 andpassing over the 40 depends from the arm 39 and passes through a slot 41in the lower faceof the guide bar 37 and to which the free endof thecord section -CZ- is attached as shown Y in Figure 2, the cord passingthrough the opening' 13 in the top wall of the housing 13. A coil spring42 is attached at one ofl its Vends to the housing 13 and at its other Alug end to the cord section nclthereby placing all of the cord,vsections under proper tension. In order' to hold the sliding latchoperating arm 39 at its limit of movement in one direction, the spring43 is connected at one end to the outer end of the bar 37 and has itsother end connected to the lug' 40 as clearly shown in Figures 2y and 3,the springs 42 and 43 maintaining the cord sec-k tions and sliding armproperly positioned. As shown in Figure 2, a block 44 is carried by theouter end of the sliding arm 39 and i has pivoted thereto one end of alatch oper#V ating arm 45, a wire spring 46 being inter-` posed betweenthe arms 39 and 45 for maintaining the pivoted arm 45 resilientlyelcvated and limited by the strap guide frame 47. A latch casing 48 issecured to the in ner wall of the housing 20 and has the nose 49 of thesliding latch bolt extendingfroin the latch casing into thel opening'20in the? housing 20, a ring 50 carriedvb'y the sliding bolt extendingthrough a slotin the casing 49 and into which ring the free end 51 ofthetically slidable board 54 is resilientlyvmou'nt- Y l f ed, guide pins 55being carried by the lowerk ends of the guide bars 53 and extending'into slots 56 formed in the lower end of the board 54 while coil springs57 surround the guide rods 55 betweenthe lower endsof the bars 53 andthe board 54 thereby resiliently supporting the trip boards 54. As shownin VFigures 4 and 6, Vthe trip boards54 extend upwardly through slotsV58 in the platform 52 and the meeting edges of trip boards 59' rest onthe upper projecting end'thereof, the

trip boards 59 being anchored to the platform i 52 by the spikes 60entering the platform` through slots 61 in the platformiboards 59. Asupporting frame 62 depends from the platform 52 and a pair of pulleys63 and 64 journaled therein. As shown more clearly in Figures 4 and 5, alever 65 is pivoted as lever 65, the free end of the lever as shown inFigure 6 being provided with an opening v 68 for the reception of thefree end of either of the cords -aor -Z-. To effect the release of thelatch lever 25 from the keeper lug 27 simultaneously with the shiftingof the gate operating cords, a lever 69 is pivoted as at 70 to the edgeof each board 54 and has one end thereof positioned for engagement withthe standard pin 71 upon the guide bar 53 while the other end of thelever has a cord connection 72 which cordS72 from the separate tripdevices 14 and 15 pass over sheaves 73 secured to the lower end of thestandard 24 for engagement as at 74 with the free end of the lever latch25.

Assuming that the gate is in the closed full line position shown inFigure 1 and it being desired to swing theV gate upon its hingedmounting v11 as indicated by the arcuate line 10 in Figure 1,'the weightof a vehicle upon either of the platform Vvboards 59 will depress thevertically sliding board 54 operating the lever 69 to release the leverlatch 25 fromvthe keeper lug 27. Simultaneously with this movement, thelever 65 will move upon its pivotal connection 67 with the hanger 67 toelevate the end thereof connected to the cord -a-, moving the cord overthe pulleys 64 and 63 and by the cord connection -Z)- with the disk 21of the gate will swing the gate against the tension of the spring 22 toposition the keeper 49 carried by the swinging end ofthe gate 10 in theopening 20 of the housing 20 for engagement with the latch bolt 49,thus'retaining the gate in its open position agalnst thevv tension ofthe sp-ring 22. The over-V balancing of the lever latch 25 will retrievethe slack in the cords 72 and present itself for engagement by thekeeper lug on the v gate 10 when again closed. After a vehicle haspassed through the gate opening the other trip device is operated andthrough the cordconnections -a-. to -dwith the sliding arm 39, said armis movedkin fthe guide bar 37 to cause the pivoted arm a3 shia the nachboit 49, thereby 'freeing the latch bolt from engagement with the keeper49 upon the swinging gate 101130 permit the spring 22 to return the gateto its closed position with the keeper lug 27 upon the opposite face ofthe gate again engaging `the lever latch 25. It will therefore be seenthat the forcible loweringv ofthe ver- `tically sliding boards 54against the supporting springs 55 will effect'a positive rotation of thegate'upon its hinge mounting 11 against the tension of the spring 22 andpresent the keeper 49 carried thereby for engagement by the latchbolt'49, and also, that a subsequent operation of either of the tripdevices will eifect the operation of the latch bolt 49 to disengage thesame from the keeper 49 carried by the-gate whereupon the spring 22 willreturn the gate to l its closed position. While there is herein shownand described what is believed to be the preferable embodiment of theinvention, it is nevertheless to be understood that minor changes may bemade therein without departing from the spirit and scope of theinvention as claimed.

W'hat isclaimed as new is: 1. Gatev operating mechanism comprisin aswinging gate, independent means for holding the gate in open and closedposition,.a"trip device arranged at each sidevof the gate, cordconnections between thetrip devices and the gate adapted upon operationof the trip devices to the gate to open position orv engagementby theholding device, means operated by the trip devices for releasing themeans for holding the Vgate in closed position, the deositively movevice for holding the gate inopen `position vice for holding the vgate inopen position comprising a 'sliding latch, a shiftable arm connected tosaid. latch and operated by the connecting cords, and meansv forresiliently holding the shifting arm in engagement with the slidinglatch.
